问题 I want to build 3 step user registration with avatar uploading on 2nd step. So i follow Ryan Bates's guide http://railscasts.com/episodes/217-multistep-forms . I'm using CarrierWave gem to handle uploads. But it seems like i can't store uploaded file info in user session (i'm getting can't dump File error).

I am almost sure that the issue is caused Carrierwave and fog gems to use amazon s3. But I am not sure exactly in which folder the issue is!

问题 Let's say my model has an image with :thumb and the client wants :tiny and :nano thumbnails. How do I reprocess all the existing images using a rake task?
